Meta-heuristic algorithms are often inspired by natural phenomena, including the evolution of species in Darwinian natural selection theory, ant behaviors in biology, flock behaviors of some birds, and annealing in metallurgy. Due to their great potential in solving difficult optimization problems, metaheuristic algorithms have found their way into automobile engine design. There are different optimization problems arising in different areas of car engine management including calibration, control system, fault diagnosis, and modeling. In this paper we review the state-of-the-art applications of different meta-heuristic algorithms in engine management systems. The review covers a wide range of research, including the application of meta-heuristic algorithms in engine calibration, optimizing engine control systems, engine fault diagnosis, and optimizing different parts of engines and modeling. The metaheuristic algorithms reviewed in this paper include evolutionary algorithms, evolution strategy, evolutionary programming, genetic programming, differential evolution, estimation of distribution algorithm, ant colony optimization, particle swarm optimization, memetic algorithms, and artificial immune system.

The effective way of reducing the vibration transmitted from the engine to the supporting structures is use of mounts. The mounts are used not only to isolate the vibration but also to withstand the static and dynamic loads of the engine. In this work, the mount structural materials are prepared from steel, cast iron and epoxy granite and tested for the structural properties and damping ratio. The mounts manufactured using these materials and natural rubber are tested using the experimental setup for the dynamic behavior with harmonic excitations. The results of the reaction forces exerted and the respective phase angles during the harmonic excitations showed that the epoxy granite-rubber mount has improved natural frequency and vibration isolation.

“…The EM consists of a cylindrical steel structure fixed to a rubber core, and it is exposed to forced vibrations caused by the engine operation [3] to [5]. The forced vibrations could cause failure due to fatigue of the EM rubber core, limiting the EM lifetime to five or six years at most.…”

A rubber engine mount (EM) is a mechanical coupling between the engine and the chassis, and its main function is to diminish, in the chassis, the amplitude of vibrations caused for the engine operation. Such vibrations cause discomfort for vehicle passengers and reduce the EM lifetime. To increase the comfort of vehicle passengers and the lifetime of the EM, this paper presents an EM optimization by means of reducing three main criteria: the EM mass, the displacements transmitted to the chassis, and the mechanical stress in the EM rubber core. For carrying out the EM optimization, the optimum global determination by linking and interchanging kindred evaluators (GODLIKE), assisted by artificial neural networks (ANN) and finite element method (FEM), was used. Because of the optimization process, a reduction greater than 10 % was achieved in the three criteria in comparison with a baseline design. The frequency responses were compared and showed that although the optimization was carried out for the range of 5 Hz to 30 Hz the trend of reduced responses continues beyond this range. These results increased the comfort of vehicle passengers and the lifetime of the EM; in addition, the reduction of mass diminishes its production costs.
